Do not plug a phone jack connector into any RJ-45 port. This may damage the
switch. Instead, use only twisted-pair cables with RJ-45 connectors that conform
with FCC standards.
Notes: 1. When using Port 8MDI-X on the ES3008A, do not use Port 8MDI.
2. Make sure each twisted-pair cable does not exceed 100 meters (328 feet).
3. We advise using Category 5 cable for all network connections to avoid
any confusion or inconvenience in the future when you upgrade attached
devices to Fast Ethernet.
Making a Connection via an MDI Daisy-Chain Port
To connect to another compatible switch or hub, take these steps:
1. Use the RJ-45 daisy-chain port (i.e., Port 8MDI on the ES3008A, Port 16MDI
on the ES3016A). When using the ES3016A, set the daisy-chain switch to
MDI and connect to any MDI-X station port on the other device. Alternatively,
you can connect from any RJ-45 MDI-X port on the switch to an MDI daisy-
chain port on the other device.
2. Prepare straight-through shielded or unshielded twisted-pair cables with
RJ-45 plugs at both ends. Use 100 Ω Category 3, 4 or 5 cable for standard
10Mbps Ethernet connections, or 100 Ω Category 5 cable for 100Mbps Fast
Ethernet connections.
3. Connect one end of the cable to Port 8MDI on the switch, and the other end to
any MDI-X station port on the other device. When inserting an RJ-45 plug, be
sure the tab on the plug clicks into position to ensure that it is properly seated.
Notes: 1. When using Port 8MDI on the ES3008A, do not use Port 8MDI-X.
2. Make sure each twisted-pair cable does not exceed 100 meters (328 feet).
3. To connect to another switch or hub, you may also attach to (MDI-X)
station ports at both ends if you use crossover cabling. (Refer to “Port
and Cable Assignments” on page 9 for a description of crossover cable.)
Restrictions on Cascade Length - The IEEE 802.3 standard recommends
restricting the number of hubs (i.e., repeaters) cascaded via twisted-pair cable to 4;
while IEEE 802.3u provides even stricter recommendations for Fast Ethernet.
Therefore, when cascading devices other than this switch, please refer to the
accompanying documentation for cascade restrictions. However, note that because
switches break up the path for connected devices into separate collision domains,
you should not include the switch or connected cabling in your calculations for
cascade length involving other devices.
Powering On the Switch
1. Plug the power cord into the power socket at the rear of the switch, and the
other end into a power outlet.
2. Check the LED marked Power on the front panel to see if it is on. The unit will
automatically select the setting that matches the connected input voltage.
Therefore, no additional adjustments are necessary when connecting it to any
input voltage within the range marked on the rear panel.
